Mechanical Components
Inspect all mechanical components
Guide Rail Spec
Check inner guide rails for spec. Make sure all hardware is tightened and in the right spots. Inspect the guide rod that the rails slide on. Inspect the outer hardware that holds the guide rod in place.
Tie Rods
Inspect all tie rods. Check for tightness, scarring on shaft, threads, and any other point of weakness. Make sure to tighten the jam nut with a 30mm wrench.
Spar Racks
Check all 3 spar racks. Inspect all teeth on both the rack and the jig. Make sure all bolts and washers are in place and tightened. Take a 10mm Allen with a 1/2 drive ratchet and hit all 4 bolts on each side of rack. Make sure all bolts are in teeth jig attached to the nailing beam. Replace or tighten if needed.
Nailing Beams
Check all 3 nailing beams. Inspect for any abnormalities. Make sure all nailing beams are square to the dogs. Check inside beam for obstructions. Verify all debris is clear from tie rods.
Clinch plates and black guides
Inspect all clinch plates and the plastic guides. Check for wear and tear and make sure the nail chucks are aligned with the clinch plates. Check guide thickness and put it in comments.
Doors
Inspect all 4 doors. Make sure all doors are within the track. Verify all hardware for doors and track are accounted for and tightened.
Hydraulic Components
Check all hydraulic components including fittings, hoses, and cylinders.
Check Hydraulic Cylinders
Inspect all 9 hydraulic cylinders. Make sure to check in the up and down position. Inspect for leaks, wear, and any other abnormalities.
Inspect hydraulic hoses and fittings
Inspect all hydraulic hoses within the lower part of the nailer. Check for any abrasions, leaks, and tightness. Hit all fittings with a 36mm wrench. If the inner fitting spins take off the hose and tighten fitting with 32mm wrench.
Hydraulic Pins
Inspect upper and lower pins on all 9 cylinders. Make sure all bolts are accounted for. Check all hardware for tightness. Tighten all bolts with a 17 or 19mm wrench on both sides. DO NOT use an impact.
Electrical Componenets
Inspect all electrical components in the bottom part of the nailer and verify all are working as intended.
Slow down and Nailing Limit switches
Inspect the slow down and nailing limit switches. Check the hardware and cabling for wear and tear. With another technician check for functionality to the screen. Verify all hardware is tight.
Beam Sensors
Inspect all upper and lower beam sensors. Check the hardware and cabling for wear and tear. Verify all sensors are functioning properly.
Door sensors
Inspect all 4 door safety sensors. check hardware and cabling for wear and tear. Verify all sensors are functioning properly.
Pneumatic Components
Inspect all pneumatic components on the bottom part of the nailer.
Air cylinders
Inspect all 12 actuators. Inspect for leaks in the up and down positions. Verify all fittings and hoses are free of leaks and inspect for wear and tear. Check all hardware. Make sure the long 12mm bolt holding the actuators down is intact and free from debris.
Air hoses
Inspect all air hoses and fittings for leaks
Solenoids
Check all solenoids on the bottom part of the nailer. These are located on the upper part of the beams inside on the nonoperator side. Verify they are free from debris and in good working order.
